Sagot :
Answer:
The frequency of light beam is 4.74 x 10^(14) s^(-1)
Explanation:
In this problem we use the formula C=F x ( lamda )
here c= the speed of light
f =the frequency of light beam
lamda = wavelength
c=3 x 10^8 m/s ( universally same)
lamda = 633nm = 633 * 10^(-9) m
Therefore f = c/ ( lamda )
or; f = 3 x 10^8 / 633 * 10^(-9)
f= 4.74 x 10^(14) s^(-1) .
